File creation with location limitation capability in storage cluster environments
A system, method and program product for creating files in a cloud environment having a storage cluster. As system is provided having a command processor that parses an inputted file creation command and determines whether a location tag is specified for a file being created and stored in the storage cluster; and a location limitation processor that, in response to the location tag being specified: retrieves a creation limitation profile associated with the location tag; causes the file to be created with a location limitation in the storage cluster based on the creation limitation profile; and stores an identifier for the creation limitation profile in an extended inode structure.
1. A file creation system for a storage cluster, comprising:
a command processor that parses an inputted file creation command and determines whether a location tag is specified in the file creation command for a file being created and stored in the storage cluster; and
a location limitation processor that, in response to the location tag being specified: retrieves a creation limitation profile associated with the location tag; causes the file to be created with a location limitation in the storage cluster based on the creation limitation profile; and
stores an identifier for the creation limitation profile in an extended inode structure corresponding to the file; wherein the extended inode includes a set bit that indicates whether or not a location limitation condition exists.
2. The file creation system of claim 1 , wherein the location limitation includes at least one of a specified data center, a specified server, a specified storage logical unit number (LUN), or a specified data volume.
3. The file creation system of claim 1 , wherein the creation limitation profile is retrieved from a plurality of creation limitation profiles.
4. The file creation system of claim 3 , where the plurality of creation limitation profiles are stored in at least one XML file.
5. The file creation system of claim 1 , further comprising a user interface that includes a dropdown menu that lists a plurality of location limitation options.
6. The file creation system of claim 1 , wherein the extended inode includes a field for storing the identifier.
7. The file creation system of claim 1 , wherein the location limitation processor interacts with an operating system kernel to create files with location limitations.
8. A computer program product stored on a computer readable storage medium, which when executed by a computing system, provides a file creation system for a storage cluster, the program product comprising:
program code that parses an inputted file creation command and determines whether a location tag is specified in the file creation command for a file being created and stored in the storage cluster; and
program code that, in response to the location tag being specified:
retrieves a creation limitation profile associated with the location tag; causes the file to be created with a location limitation in the storage cluster based on the creation limitation profile; and
stores an identifier for the creation limitation profile in an extended inode structure corresponding to the file; wherein the extended inode includes a set bit that indicates whether or not a location limitation condition exists.
9. The program product of claim 8 , wherein the location limitation includes at least one of a specified data center, a specified server, a specified storage logical unit number (LUN), or a specified data volume.
10. The program product of claim 8 , wherein the creation limitation profile is retrieved from a plurality of creation limitation profiles.
11. The program product of claim 10 , where the plurality of creation limitation profiles are stored in at least one XML file.
12. The program product of claim 8 , further comprising a user interface that includes a dropdown menu that lists a plurality of location limitation options.
13. The program product of claim 8 , wherein the extended inode includes a field for storing the identifier.
14. The program product of claim 8 , further comprising program code that interacts with an operating system kernel to create files with location limitations.
15. A computerized method that provides file creation for a storage cluster, comprising:
parsing an inputted file creation command;
determining whether a location tag is specified in the file creation command for a file being created and stored in the storage cluster;
retrieving a creation limitation profile associated with the location tag;
causing the file to be created with a location limitation in the storage cluster based on the creation limitation profile; and
storing an identifier for the creation limitation profile in an extended inode structure corresponding to the file; wherein the extended inode includes a set bit that indicates whether or not a location limitation condition exists.
16. The computerized method of claim 15 , wherein the location limitation includes at least one of a specified data center, a specified server, a specified storage logical unit number (LUN), or a specified data volume.
17. The computerized method of claim 15 , wherein the creation limitation profile is retrieved from a plurality of creation limitation profiles.
18. The computerized method of claim 17 , where the plurality of creation limitation profiles are stored in at least one XML file.
19. The computerized method of claim 15 , further comprising providing a user interface that includes a dropdown menu that lists a plurality of location limitation options.
20. The computerized method of claim 15 , wherein the extended inode includes a field for storing the identifier.
